He has a small following outside Japan thanks to a couple of notorious films:Entrails of a Beauty and Entrails of a Virgin. This type of film (low budget, yet high production values and shot on video), helped usher in a new era of extreme Asia movies. Komizu was the creator of the Japanese cult zombie film Battle Girl: The Living Dead in Tokyo Bay which was screened in 1991.^[1]

His nickname, "Gaira", apparently comes from a Japanese monster in the film War of the Gargantuas (フランケンシュタインの怪獣 サンダ対ガイラ, Furankenshutain no kaijū: Sanda tai Gaira) (1966).
